I'm thinking of combining these 2 plants in a hanging basket.
Since I don't want to give up the climbing aspect, I'm going to use a roll of wire to turn the hanging arms into a trellis. If I use extra-long, home-made hanging arms also made out of wire, it should give them enough height that it would take a while for them to fill it up. There's a hanging pot with really long home-made wire arms, photo-bombing the main plant in this pic, on the right. I may try to find an existing pot to squeeze them into this way...
Here's some cool aerial roots on some Pothos and Monstera climbing up a wood board support. Scindapsus is just starting to get in on that action too.
Mere lack of space isn't going to stop me from adding more cool plants. Just need to be creative about making the existing pots more useful. What other things are folks doing with their vines? To save space?
